I would put them in “doc”.

“4.3.2” looks good. If need be, the numbering scheme can always be
adjusted later.

Rather put this in ‘snippet’ (I think Mark made this comment on IRC.)

What about “C++ library for parallel programming” instead?

I would indeed remove the 2nd paragraph, and perhaps add something like
“It provides parallel loop constructs, asynchronous tasks,
synchronization primitives, atomic operations, and more.”

Rather: “GPLv2 with run-time exception:
<https://www.threadingbuildingblocks.org/licensing#runtime-exception>”.
